SPECIFCATION forming part of Letters Patent No. 727,534, dated Ma'y 5,1903. Application led December 9, 1902. Serial No. 134,580. (No model.)

To @ZZ whom, t may concern:

Beit known that I, SAMUEL M; CAWKER, a

citizen of` the United States of America, re-4 sidingin the city ofDenver and State of Colorado, have invented certain new and usefulImprovements in Non-Refillable Bottles; and I do declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, `ref erence being had to the accompanying drawings, and tothe figures of reference marked thereon, which form a part of thisspecification.

My invention relates to improvements in non-reiillable bottles; and itconsists in locating in the neck of the bottle an air-storage chamberinto which suflicient air or gas may be compressed to lill the bottle,the said chamber having a valve controlled from the outside, whereby airor gas may be admitted to the bottle to force the liquid out. The air inthe said chamber is compressed to a number of atmospheres, so that whenreleased it will expand to fill the bottle at normal atmosphericpressure, but no more. Hence after the bottle is once emptieditcannot berefilled, or, if refilled, it cannot be emptied, as there is noopportunity for air or gas to get into the bottle to take the place ofthe liquid, the receptacle or chamber in the neck of the bottle havingno communication with the external atmosphere. Provision is also madefor locking the valve in the closed position as' soon as the bottle isempty, so that if the receptacle was bored to let in air it could notescape into the bottle by the manipulation of the valve or otherwise.

Having briefly outlined my improved construction, as well as thefunctions it is intended to perform, I will proceed to describe thesame-in detail, reference being made to the accompanying drawings, inwhich is illustrated au embodiment thereof.

In the drawings, Figure lis a section taken through a bottle equippedwith my improvements.v Fig. 2 is a sectional view of the airchambershown in detail and on a larger scale. Fig. 3 is a section taken on theline 3 3, Fig. l. Fig. 4. is a fragmentary section of the air-chamber,showing the valve-stemlocking device held open to allow the stem to movefreely. Fig. 5 is a similar View showing the locking device released.These views are taken on the line 4 5,`Fig. 2, viewed in the directionof the arrow.

The same reference characters indicate the same parts in all the views.

Let the'numeral desiguate the neck of the bottle, in which is located acylindrical airchamber 6, the latter being provided with eX- terior ribs6 and held in place by cement 7. Formed in the neck of the bottleadjacent the chamber 6 is a recess in which is located a tube or conduit8, preferably composed of glass and extending into the lower part of thebottle, preferably terminating as close to the bottom as practicablewithout closing the open end ot' the tube. This is preferably providedexteriorly with a bent portion 8, whose free end is directed downwardlyfor convenience in drawing the liquid from the bottle. Passing throughthe chamber 6 is a tube 9, which is secured in the heads 6a and 6c ofthe chamber, the latter being preferably composed of steel or othersuitable material adapted to give the required strength with aminimumweight and thickness. This tube passes through the lower head or bottom6 of the chamber and protrudes sufficiently to form a nipple for theattachment of an air-pump, which may be employed in compressing the airwithin or charging the chamber 6. For this purpose the protruding end ofthe tube is threaded, as shown at 9a. Within the tube 9 is located asteml0, whose lower extremity is tapering and forms a valve, which fitsclosely in a counterpart seat formed in the-lower portion of the tube.The lower extremity of this stem is outwardly flared to engage ashoulder formed on the tube to prevent the withdrawal of the stem fromthe tube. This tapered portion of the stem is hollow, as shown at 10a,and this hollow portion communicates with a transverse opening 10,formed in the stem and adapted when the latter is properly adjusted toregister with an opening 9, formed in the tube and communicatin g withthe air-space within the chamber. Above the orifice 10c a recess l0d isformed in the tube to receive a stud 12, mounted on a leaf-spring 13,attached to the tube 9 and lo- ICO 2 'ret/,534.

cated in the chamber. This tube is provided by air from the chamber 6escapesv into the with an opening 9g to receive the stud, and when thestem lO is properly adjusted the spring throws the stud into the recess10d and locks the stem 'from turning. Therelative arrangement of theorifices 9C and 1,0c is such that when the stud 12 engages the recess10d the said orifices do not register, and consequently there is nocommunication between the chamber 6 and the interior of the bottle whenthe stem is locked. The lower extremity of the spring 13 is bent tooccupy a horizontal position, as shown at 13, and this horizontalportion is provided with a notch 13e. Mounted on the bottom or lowerhead of the cylindrical air-chamber is a Hexible diaphragm 14, having aspace beneath closed from the space within the chamber, butcommunicating with the bottle by an orifice 15. Normal atmosphericpressure keeps this diaphragm raised, and mounted upon it is aprojection 16, adapted to engage the notch of the spring and hold thelatter outwardly, whereby the studV is prevented from entering therecess of the stem 10. Before the chamber 6 is closed and sealed thespring 13 is drawn outwardly and the stem turned to prevent the stud 12from entering the recess 10d, and so that the orifices 9c and l0c shallregister. The chamber 6 is then sealed and air introduced by connectingan air-pump (not shown) with the threaded protruding part 9 of the tube9. The air is compressed in this chamber until the pressure-gage (notshown) indicates a pressure of a number of atmospheres equal to thenumber of times the volume of the air-chamber is contained in the volumeof the bottle. If the contents or" the bottle equal twenty times thecontents of the air-chamber, the pressure-gage must indicate twentyatmospheres, which at the sealevel would be three hundred pounds. Ofcourse the pressure in pounds required in any given case will vary withthe elevation, but the relative number of atmospheres of course nevervaries. The required pressure in the chamber 6 will depress thediaphragm let and bring the projection 16 into the notch 13c of thespring, thus preventing the stud from entering the recess 10 of thedevice and permitting the stem` to be turned freely Without danger oflocking by engagement with the stud. As soon as the air-chamber isprepared-that is to say, as soon as the pressure therein reaches theproper number of atmospheres, as indicated by the pressure-gagethe stemis turned to cut off communication between the orifices 9C and 10C, thusclosing the chamber to prevent the escape of air. The ai-rchamber isthen placed in the neck of the bottle, the latter being first iille'dwith its liquid contents and securely sealed by the use of cement or inany other suitable manner. Then whenever it is desired to draw liquidfrom the bottle or other vessel containing my invention the stem 10 isturned to cause the orifices 9c and 10c to register, wherebottle andforces the liquid out through the tube 8 into a glass or otherreceptacle held beneath the nozzle of the part 8% After the liquid hasvall been drawn out of the bottle there will be normal atmosphericpressure in the air-chamber and bottle and the diaphragm 14E will riseand release the spring 13, and as soon as the stem 10 is turnedsufficiently the stud 12 will enter the recess 10d and lock the stemagainst turning. There is now no way to get more air into the chamber 6Without boring a hole in the upper head of the airchamber, and if thiswas resorted to there would be no way of releasing the airto control thedischarge of the liquid from the bottle even if the latter could berefilled. Hence the device may be properly called a non-re fillablebottle.

It must be understood that wherever the term air is used in thespecification and claims air or gas must be understood, since it isevident that gas, wherever' practicable, may be employed as well as airfor filling the air or gas chamber without in any Way de# parting fromthe spirit of the invention.
